What do you do when you flop a monster on a steal?

Man, party is rocky today. I've stolen on this tight table maybe 8 times so far in late position/small blind, big blind is Semi-tight and semi-aggressive and with all the steals I've done by now he'd play back at my suspected unimproved overs with any piece of the flop, I suspect.

Getting too fancy? Would you rather 3 bet the flop? How about Stop and Go on the turn and not risk giving him a free card rather than check/raise?
